Always thin out damaged, diseased, and crossing branches annually. Heading cuts are those that clip a branch only partway back. Indiscriminate heading cuts will stimulate more vegetative growth and delays proper flowering. Continual heading cuts will totally prevent the flowering of apples and pear trees.
Apples , pears , European plums , and cherries perform best when trained as a central leader-shaped tree. The central leader should be headed back each year. This is the one exception for use of the heading cut option.
Peaches , nectarine , Japanese plums , and apricot require both heading and thinning cuts. Perform best when pruned into vase-shaped with no central leader. Their fruits are produced on one-year-old wood. Did you get a late spring frost? Once flower buds begin to swell and develop there is a risk of frost damage. If there was a frost possibility, wait one day then check blooms. Dark brown-black centers in bloom mean, sadly no fruit that season. Extreme temperatures in mid-winter can also damage bud tissue, and mild temperatures in mid-winter that cause sap to flow, then are followed by rapid dropping temperatures can cause not only fruit problems but can sometimes kill an entire tree, especially young trees.
Apricot flower buds are extremely sensitive to late frosts. This should be considered when sight selection is being considered for apricot trees. March— For existing trees, prune before growth begins, after coldest weather has passed. Before choosing an apple tree to plant, take a look around your neighborhood. A pollen source should be within feet of the apple tree you plant to ensure the pollen gets to your tree.
If you don't see any crabapples or other apple trees that close, your best bet is to plant two trees of different varieties. When purchasing an apple tree, you are actually selecting a plant made up of two genetically different individuals grafted together, the scion and the rootstock.
Variety tables provide hardiness, size and compatibility information for apple varieties that have proven to do well in northern climates. If you have limited space, pay particular attention to the rootstock you choose for your apple trees.
Often nurseries will label the trees dwarfing, semi-dwarfing, and standard. These labels are referring to the rootstock, which determines how tall your tree will grow. If you have an interest in a specific rootstock, talk with your local nursery. They might be able to order a tree for you. Otherwise, you might want to order trees from a nursery that grafts each fruit variety on various rootstocks to get the combination you desire.
A seedling rootstock is actually grown from the seed of an apple, often McIntosh or another common, hardy variety. Although you won't know exactly what you're getting with a seedling rootstock—every single seed is a genetically different individual —hardiness, anchorage and adaptability to different soil types are generally excellent. In many areas of Minnesota, this can work out to roughly a foot tree. It produces fruit very early in the life of the tree. It produces moderate amounts of root suckers and burr knots.
This dwarfing rootstock produces a tree feet in height. Trees planted on M. Fruit is produced very early in the tree's life, sometimes within three years from planting. Apple trees require full sun, so choose a spot where the sun shines directly on the tree for at least 8 hours each day. When it comes to soil, apple trees can grow in most soils as long as there is no standing water and the pH of the soil is between 6 and 7. If you are unsure about your soil pH, conduct a soil test to determine soil conditions before planting and amend the soil as suggested by the results.
How much space do you need for apple trees? A good rule of thumb for a garden fruit tree is to provide at least as much horizontal space as the anticipated height of the tree. So, if your tree will grow up to 8 feet high, make sure there are 8 feet between it and the next tree.
Planting trees too close together will increase shading and reduce the number and quality of the fruit coming from your tree. From watering to weeding to thinning fruit, caring for your apple trees throughout the year will help your plants produce plenty of apples to harvest.
Throughout the life of the tree, you should water its root zone thoroughly during the growing season whenever there is a dry spell. Ideally, the tree should receive one inch of water from rainfall or irrigation every week from May through October. It's a good idea to stake the tree for the first few years. Either a wooden or metal stake will work. A stake should be about the height of the tree after being pounded two feet into the ground.
Use a wide piece non-abrasive material to fasten the tree to the stake. Avoid narrow fastenings such as wire or twine, as they may cut into the bark.
Planting is a good time to install a tree guard. These are usually made of plastic and are available at most nurseries and online.
Tree guards protect your tree from winter injury and bark chewing by small mammals, such as voles aka meadow mice and rabbits.
Guards also reflect sunlight from the trunk, which helps prevent the trunk from heating up on a cold, sunny winter day. Once the tree has rough and flaky mature bark, neither winter sun nor chewing animals can harm it, so tree guards will not be necessary. For the first years of its life, however, it's important to protect the trunk of your fruit tree.
Once established, an apple tree planted on a favorable site, in properly prepared soil, should thrive with minimal fertilization. An apple tree will provide an abundant crop if conditions are favorable when the tree is in bloom. Some of the fruit will naturally drop off the tree in mid June, but the tree may be left with more fruit than it can support. Too heavy crops can cause biennial bearing, when a heavy crop of small, green apples is followed by little or no crop the next year.
The color of an apple is only one indicator of its ripeness. Sweetness is an indicator of maturity and harvest-readiness along with fruit size and color. There is a popular idea that some later apple varieties need a frost to sweeten them before picking.
However, apples will ripen and sweeten up without a frost. Although garages, basements and root cellars may provide adequate storage conditions, the best place to store apples at home is usually the refrigerator. Fruits such as apples, grapes, and strawberries are high in sugar. A brief dip below 28 degrees may just weaken the apples enough to decrease their shelf life. Several nights below 28 degrees are more likely to soften the skin and flesh of the apple, making the fruit unusable.
If only a brief freeze happens and the fruit is still firm, use the fruit soon, as it may not store well. Prune a tree to have well-spaced branches and a balanced appearance, while eliminating broken, diseased or dead branches.
Prune minimally, especially with young trees, as excessive pruning will delay or reduce fruiting and create too much leafy growth. Once the first set of scaffold branches has been selected, select a second set above it. Scaffold branches should be spaced about 12 inches apart. Always keep the conical form in mind when pruning. Many apple trees are pruned and trained to allow a central main stem, or leader, to be the foundation of the tree off of which side branches, or scaffolds grow.
The tree ends up with a conical or pyramid form. This is called central leader pruning. This is a simple pruning method, and it makes for a compact, balanced, easily managed tree, with fruit that has maximum access to sunlight and air circulation. Have you moved into a house that has an old, overgrown apple tree? Are the branches overlapping and going every which way? Don't lose hope. This tree is probably fine, it just needs a little work to get it back in shape and productive again.
Reclaiming a mature apple tree that has been neglected for several years can be a challenge, and will take a few years of pruning to make the tree productive again. Here are a few guidelines for renovating a neglected tree:.
As you prune your young tree to achieve a good form, you may also need to train it. Training primarily consists of bending young, flexible branches that are growing vertically into more horizontal positions, toward a 60 degree angle from the main stem. This tends to be a quality in modern commercial apple varieties, since the earlier the tree starts bearing the earlier the owner starts to get a return on his investment.
Granny Smith and Braeburn are precocious, as is the well-known English Conference pear. Conversely, some varieties are naturally slow to come into bearing - a number of well-known traditional American varieties fall into this category, such as Northern Spy, and Wolf River. Using precocious rootstocks and other techniques can help to encourage these reluctant varieties to get into fruiting earlier - or of course you can just let them come along at their own pace.
If you have a semi-vigorous or vigorous fruit tree and it is still not fruiting, there are several things you can do:. Firstly, in spring, tie any new shoots down to a horizontal position whilst they are young and whippy.
The easiest way to do this is to plant a tall bamboo cane alongside the branch and gently tie the branch down to the cane. It won't look pretty but after a few months you should be able to remove the cane and the branch will stay in position. The reason this works is that the act of tying the branch down simulates the weight of ripening fruit on the branch - and this in turn encourages the tree to set fruit buds over the summer which will produce blossom and fruit the next year.
This technique works particularly well with apple trees. Secondly, don't prune the tree. Pruning will either simply encourage the tree to put on more growth, or in some cases you may accidentally cut off the fruit buds that will form next year's crop. It is worth remembering that next year's blossom and hence next year's fruit is formed the preceding summer. Don't over-feed the tree. One application of general plant food in spring is sufficient, along with watering when required.
Over-feeding generally causes the tree to produce more branches and leaves, not more fruit. Most gardening books stress the importance with young apple trees of picking off any fruitlets that form in the first few years after planting. There are many factors to consider when selecting apple trees, the first and foremost being how to choose the correct plant for your particular environment.
The speed at which apple trees grow might also be important in your decision-making process, as some varieties produce earlier in their lives than others. When choosing to grow an apple tree, remember that apples need cross-pollination to bear fruit, so you need to have a partner plant nearby.
One of the most instantly recognizable types of apple is the Red Delicious apple. These iconic fruits are the most popular apple grown in the United States because they are sturdy and hardy and reach maturity quickly, fruiting within 7 to 10 years of planting. Dwarf varieties fruit in 3 to 4 years. Another delicious alternative with a similar growth speed is the Golden Delicious apple.
Lodi apple fruit is another great option that can be grown across most of America. They produce fruit quite early in the season, making them an absolute delight for eager gardeners. As a bonus, they are tolerant of many different types of soil. At standard size, they fruit within 6 to 10 years. The Gravenstein apple tree is a must-have for apple growers in a hurry. Among the largest apple trees, they can produce large quantities of apples within 2 to 5 years of planting and grow well in almost all hardiness zones.
A slightly fussier apple tree temperature-wise is the Fuji apple tree. However, it also reaches maturity quickly and can start to bear fruit at 3 to 4 years.
These fairy-tale trees reach maturity at around five years and are considered one of the more ornamental varieties. While most types of apple trees can grow in many different types of soil, poor soil will yield poor harvests.
Their optimum growing environment is sandy soils and loams that are well-draining, slightly acidic, and fertile. Soggy soil can result in inadequate aeration, stunting root growth, and fungal infections. This may inhibit the production of healthy apples.
Before planting, adding a little lime to turned soil helps to raise pH levels.
